SULKY MARROW AND PULVERIZER.

Application filed August 28, 1890. Serial No. 363,258. (N model.)

To aZZ whom it may concern: tivating devices, which may be of any suit-Be it known that 1, CHARLES D. ROBERTS, able construction, but which arepreferably a citizen of the United States, residing at Fairconstructedas follows: field, in the State of Illinois, have invented In Fig. 1 theframe is shown as connected 5 certain new and useful Improvements in toa V-shaped harrow, which is composed of Sulky Harrows and Pulverizers,of which the the rearwardly-diverging tooth-beams H H following is aspecification, reference being suitably bolted to transverse bars F F,which had therein to the accompanying drawings. are in turn bolted tothe longitudinal draft- Referring to the accompanying drawings, beams EE, these beams being connected and ro Figure 1 represents a perspectiveview of my braced by a transverse beam F, this beam improved cultivator,one of the wheels being F not being connected directly to the harremovedto better show the parts; Fig. 2, a row-beams.

presseddown firmly against the ground by pressing down with his footupon the rear cross-beam of the harrow.

To open the front end of the harrow and slightly contract the rear endthereof, I provide the front cross-beam F with an extra row, the rearends will be contracted, the bolts g" serving as the pivotal bolts onwhich-the tootlrbea in s turn.

-' Secured to the cross-beam F, so as to be in line with. the centralline of the harrow, is a i forwardly-inclined'shovel 7L','Of suitablecon- "-struction,"which serves toform a furrow "through: the center ofthe path-of the barrow, thereby serving as a'mark or guide for acorn-planteror seed-drill. To cutaway trash wand prevent itgatheringupon the shovel, I employ a cutterh, which is secured-directlytheharrow,-and which is inclined rearwardly in front-of the shovel toablock II, carried by andsdownwardly, terminating near and in frontofthe shovel.

"cutter and shovel absolutely prevents trash i'gath'ering upon then1,thetrash thatis not i cutbeing carried down underthe shovel or forced toone side.

llIost of the trash will be cut, however, as the cutter is so arrangedas w'to exert a'draw cut upon'the same.

Instead ofthe harrow shown in Figs. 1 and 2,1:may'attach to thedraft-bars any suitable {apparatus for cultivating and pulverizing thesoil. i For instance,I may employ the pulveraddition to the harrow.

' To remove the harrow and substitute the x pulverizeig-and viceversa,it is simply neces- '..sary. to unhook the chains 6 and f from the d*aft-framc and remove the bolts upon which This arrangement-of the therollers c c are journaled, as is evident. It is evident that the shovelh and its cutter (shown in Fig. 1) are not used when the harrow isadjusted as a straddle-row harrow.

Having thus fully described my invention, what I claim is- 1'.
